Use the jammers device to block drone signal

If you're a drone pilot who wants to fly a drone somewhere you shouldn't, there isn't a whole lot anyone can do right now to stop you, due to a variety of legal complications that govern drones in flight and jamming equipment. However, with the development of technology, countries have found new countermeasures.
Electronic warfare (EW) experts at Northrop Grumman Corp. are moving to full-rate production of common open-architecture RF jammers for infantry, land vehicles, and fixed sites to protect U.S. and allied warfighters from radio-controlled improvised explosive devices (IEDs).
There's no clear FAA regulations for allowing police officers to interfere with or jam a drone in flight, but there are very real safety concerns that can arise from unauthorized drones, whether it be smuggling items into a prison or filming a secure location. And while things like the drone jammers device may help with that, jamming devices are still banned under FCC code, meaning that regular consumers and even private security firms probably won't be able to legally use one. That said, if regulations change and the jammers device can be legally used, it could be a helpful tool for improving drone security.
On a legal standpoint, the DroneDefender seems to be in a grey area. According to FCC regulations, federal law prohibits the operation, marketing, or sale of any type of GPS jamming equipment, including devices that interfere with cellular and Personal Communication Services (PCS), police radar, Global Positioning Systems (GPS), and wireless networking services (Wi-Fi). Officials of the Naval Air Systems Command at Patuxent River Naval Air Station, Md., are asking Insitu to provide six ScanEagle UAVs, support equipment, training, site activation, technical services, and data for the Philippines. Insitu is a subsidiary of the Boeing Co.
"You just need the RF [radio frequency] components to transmit a high-power signal in the right frequency band," Harrison said. "Jammers are readily available, you can buy GPS jammers online. It's illegal, but you can do it. And we know some of our adversaries have fielded pretty large powerful jamming systems as part of their force structure."
However, some states are proposing legislation, like in California, that would allow firefighters and authorities to take down drones if they are interfering with an emergency situation like a wildfire. Blocking approach paths to airports, hovering over fires, and flying over freeways could be considered instances where those drones can be shot down. However, whether or not officials would legally be allowed to use a radio jammer like the drone jammers device remains unclear.
